Concrete wash is beautiful and durable. The slightly uneven surface reduces slippage when used in a route of access. Because the stones are not easily stained, the less likely the concrete wash ringworm common concrete, nor is it hard to do. A small project as a stepping stone or tile is the best way to learn the technique.
Concrete is composed of a mixture of components: cement, coarse aggregate (typically gravel or crushed stone), fine aggregate (sand) and water. You can change the appearance of the concrete finished making changes to the elements; with white cement instead of gray, for example, or by using glass instead of crushed gravel colors. These options can change the look of washed concrete dramatically.
Instructions
- Choose what color or colors you want to finish tile and select the appropriate mix concrete. The ordinary ready-mixed concrete can produce a beautifully tiled gray exposed aggregate. Some manufacturers have mixed colors can also create beautiful mosaics. If you mix your own concrete, you can choose colors to mix and added to create beautiful effects. For example, Quick rete in beige and basic concrete mix with 3/8 inch (9.5 mm) of gravel Roan makes a beautiful mosaic.
- Concrete mix according to package directions, Spray pan with cooking spray, Wet concrete poured into the mold. Relieves air trapped in the wet concrete stepping on it several times, moving the mold and tapping sides and bottom of pan. It levels the wet concrete with 2×4 boards. It gives way to the edges of concrete with a spatula.
- Wait about six hours until the concrete has set. If the weather is humid, you may have to wait a little longer. Rub the surface with a stiff brush. Rinse frequently with a fine spray to remove loose concrete grains. Rinse the brush frequently too. Rubs until some of the coarse aggregates are clearly shown on the surface. Do not brush too deep, because the stones embedded for less than half are likely to come off later.
- Allow the surface to dry. Covered with a polyurethane film, let the tile to set in a warm, dry place for at least three days.
- Remove the part from the mold. The concrete will set for 28 days before reaching its maximum hardness, so handle it with care until you have passed the period setting.
